Quectel 5G/4G/3G/GNSS
M.2 form factor.





RM520N-GL is a 5G sub-6GHz module designed for IoT/EMBB applications. Adopts the 3GPP Release16 technology and supports 5G non-standalone (NSA) and standalone (SA) modes. Designed in an M.2 form factor, RM520N-GL is compatible with Quectel RM50xQ 5G module, LTE-A Cat 6 module EM06, Cat 12 modules EM12/EM12xR/EM121R-GL, and Cat 16 module EM160R-GL, which facilitate the migration from LTE-A to 5G. This industrial-grade module is for industrial and commercial applications.

The RM520N-GL series nearly covers all the mainstream carriers worldwide. Integrated GNSS receiver (supports GPS, GLONASS, BDS, and Galileo) greatly simplifies the product design and makes positioning capabilities quicker and more accurate.

Integrates built-in network protocol, and multiple industry-standard interfaces and supports multiple drivers and software functions (such as Windows7, 8, 8.1, 10, USB/PCIe drivers under Linux, Android. etc), which greatly expands its application in IoT and eMBB fields including Industrial Routers, Home Gateways, Set Top Box, industrial laptops, consumer laptops, Industrial PDAs, Rugged Industrial Tablet PCs, Cameras and Surveillance and Digital Signage.

For more details about USB TO M.2 KEY, you can click here to see its hardware and user manual.

1. Hardware Connection

【Hardware Preparation】

  • RM520N-GL × 1
  • USB TO M.2 B KEY × 1
  • 5G SIM card × 1

【Installation Guide】
Please refer to the following diagram to install the Nano SIM card (5G function should be enabled) and 5G module, and then install the heat sink, cooling silicone, and 5G antenna, see the following figure:
Using the USB TO M.2 B KEY board, the RM520N-GL 5G module can be plugged into a Linux host board such as a Windows computer/laptop, Raspberry Pi, or Jetson Nano via the USB 3.0 interface.

2. Connecting with Windows

2.1 Driver Installation in Windows
  • Refer to the hardware connection above and connect the module to the Windows PC via USB TO M.2 B KEY.
  • Install Windows-related drivers:


2.2 5G Network Speed Test
  • Under the Windows system, it is recommended to use MBIM mode for 5G networking.

In general, after installing the driver according to the section 2.1 Windows Driver Installation, the computer device manager and network connection can be identified normally.
RM520N-GL network card, as shown in the following figure:
At this point, as long as the SIM card and band of the RM520N-GL 5G module that is connected to the RM520N-GL 5G module are available in the test area, the 5G network can be obtained automatically, as shown in the following figure:

  • If the driver is installed and the Quectel USB AT Port (COM) is identified, but the RM520N-GL NIC device is not identified, it is possible that the factory default of the 5G module is not MBIM mode or you have modified it to other modes in use. At this time, you can try to use SSCOM or QCOM serial assistant, open Quectel USB AT Port (COM) to send AT command to set to MBIM mode, the command is as follows:
  • After confirming that the module can normally access the Internet through 5G, we can use network speed test tools to test the speed of 5G Internet access, the following figure is a screenshot of the actual test with speed test software:


①The actual speed measurement results are affected by the network coverage, network congestion, and base station distribution.
②As the power consumption of the 5G module is large when testing the speed, the USB TO M.2 B KEY must be connected to a full-power USB3.0 interface for speed measurement, to avoid insufficient power affecting the speed measurement or reset the module to reconnect.
③If the NIC is identified as normal, the NET light is not on, and you cannot connect to the network, you can refer to FAQ.
2.3 GNSS Positioning Test
  • Connect the passive GPS antenna to ANT3 of the module (corresponding to L1 of GNSS), note that the lettered side is facing down and the antenna is placed in an open outdoor test (note that GNSS positioning test cannot be performed in rainy weather).
  • Then SSCOM or QCOM serial assistant opens Quectel USB AT Port (COM) to send AT commands:
AT+QGPS=1        //Open GPS positioning
AT+QGPSLOC=0     //Get GPS position


When you just turn on GNSS positioning, you usually need to wait for a few minutes to get the data of GNSS positioning.
  • With GNSS positioning enabled, you can open the Quectel USB NMEA Port (COM) through SSCOM, QCOM serial assistant, or other positioning software to see the NMEA GPS positioning data output from this port, as shown below:


  • GNSS positioning test completed, AT command can be sent to Quectel USB AT Port (COM) to turn off GNSS positioning:
AT+QGPS=0        //disable GNSS positioning

3. Connect to other Linux main control such as Raspberry Pi/Jetson Nano

M.2 TO 4G/5G HAT

  • For more information about the M.2 TO 4G/5G HAT, you can click here to see its hardware and user manual.
  1. Connect to the Raspberry Pi Board

【Hardware Preparation】

  • 5G SIM Card x 1
  • RM520N-GL 5G HAT (with case) x 1 (kits included as shown below):

【Installation Guide】

  • Use the double-plug USB 3.0 cable to connect the 5G HAT, and then connect the external 5V power to the Type-C power port of the 5G HAT. As shown below:
Raspberry Pi Board Pi 4B Pi 3B/3B+ CM4-IO-BASE

  • If it is used for PI4B, there is a matching case with the following installation schematic:

【Raspberry Pi 5G Networking Guide】
Working with Raspberry Pi OS

  • It is recommended to use it in the newest Raspberry Pi OS with driver-free support.

Working with OpenWRT System

  • Please check whether the SIM card and the antenna are connected, and note that four antennas must be connected.
  • Please check the hardware connection and use AT Log to check the network connection.




RM500U-CN: based on Zhanrui
RM500Q-GL: based on the Qualcomm platform, supports GNSS positioning, mainly for China
RM500q-AE/RM502Q-AE: based on the Qualcomm platform, supports GNSS positioning, mainly for countries except for China.


The 5G module requires a lot of power, especially at the moment of network access; the power supply capacity of the Raspberry Pi is limited, and the 5V (3A) power supply can be connected to the onboard TYPE-C interface.


When using the external power supply, RM500U does not reboot after rebooting the Raspberry Pi, you can use the commands to restart RM500U.


As shown below:
AT+QCFG="usbnet",0 driver type is NDIS(QMI));
AT+QCFG="usbnet",1 The driver type is ECM;
AT+QCFG="usbnet",2 The driver type is MBIM; (RM5XXQ support)
AT+QCFG="usbnet",3 The driver type is RNDIS
AT+QCFG="usbnet",5 The driver type is NCM;


Use the following command to turn on the echo, and press Enter after entering: (Blind typing is required here)


It can be inquired at the following website:




Raspberry Pi 2B/zero, with user serial device number ttyAMA0;

ls -l /dev/serial*   

You can confirm that serial0 is the selected serial device number with the following command line, as follows:

The USB power supply capability of the Raspberry Pi is worse than that of the computer. It needs to be connected to an external power supply. Please set the switch to EXT PWR, and connect the HAT interface to a 5V 3A power supply:
